Hello, I have a problem and cannot really find something via Google and was wondering if someone could give me their thoughts on Race Conditions in select statements with Django. I have tried to put my .filter() into a transaction and use select_for_update. Though I never do any update with the data. Unfortunately, when two client request the url, the second never gets the correct data
